Ultraman: Firefly? Where the Heck Did You Send Me?

[The author may not write this very well. It won't just be Firefly; other characters may also be a little out of character, so please understand. There'll occasionally be everyday-life scenes. After some of the plot, Honkai: Star Rail characters will transmigrate, but not too many at once. Overall, it's lighthearted, with two male leads. This is not a BL novel. It's packed with jokes, and almost everyone goes completely off the rails. This is my debut novel. The stats were so bad that I rushed the ending, so I don't recommend reading it. The plot is okay, but the execution is awful.] Dao Changge: “What the hell? Where have you dumped me? Is this even still China?” “Golza? Melba? Is that Tiga? And what the hell is Firefly doing here?” “Dude, seriously? Why is Noah here too? And what the hell is this Space Beast?” “D-DIO?” Lucifer, with his inexplicable powers; Tartarus, who can practically foresee everything; and DIO, who can't be killed and can stop time for a whole minute. In an instance even worse than hell, Dao Changge declares: “I used to scream, but little by little, I lost my voice. I used to cry, but little by little, my tears dried up. I used to grieve, but little by little, I learned to endure everything. Now my gaze is as hard as stone. All that remains in my heart is resolve.” “No matter where you are or how powerful you may be, I will make sure the price you owe is paid!”
